SPECIFICATION formingpart of Letters Patent No. 562,876, dated June 30, 1896.

Application filed March 27, 1895. Serial No. 543,426. (No model.)

To all whom it may concern.-

Be it known that 1, JAMES WILSON, a resident of Jackson, in the county of Monroe and State of Ohio, have invented certain new and useful Improvements in Lubricators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in lubricators, and more particularly to such in which the lubricant is forced from the receptacle containing it to the machinery to be lubricated, the object of the invention being to produce a lubricator which shall be automatic in its action, cheap and simple in construction, positive in action, and effectual, in every respect, in the performance of its functions.

A further object is to construct a lubricator in such manner as to avoid the use of complicated parts likely to become deranged and of small inner tubes likely to become clogged by reason of incrustation from boilers.

A further object is to so construct a lubricator, adapted to be operated by steam-pressure, that the steam and lubricant will be effectually separated one from the other while the oil or lubricant is being forced from the receptacle by the steam, and to so construct the piston or plunger against which the steam acts, while forcing the lubricant from the receptacle, that the periphery of said piston or plunger will bear against the inner face of the receptacle with a pressure commensurate with the pressure of steam and oil against it.

A further object is to construct a lubricator in such manner that it can be readily filled and cleaned.

With these objects in View the invention consists in certain novel features of construction and combinations and arrangements of parts as hereinafter set forth, and pointed out in the claims.

In the accompanying drawing the figure represents an embodiment of my invention, parts of the apparatus being shown in section.

upper section 1 is at boiler-pressure, while a the steam in section 2 is at a lower pressure, or a pressure sufflcient to operate the machine, thus forming in effect high and low pressure steam pipes, and for the purposes of convenience I have throughout this specification designated the section 1 as a highpressure pipe and section 2 as a low-pressure pipe.

0 represents the cylinder of my improved lubricator, with the top of which a T-coupling a communicates by means of a short pipe I). lVith the coupling a one end of a pipe 0 communicates, the other end of said pipe communicating with the portion 1 of the steam-pipe A, so as to receive high-pressure steam therefrom, the said pipe 0 being provided between its ends with a valve 0'. The bottom of the cylinder 0 communicates with a coupling (1 by means of a pipe (1, and said coupling communicates, by means of a pipe c, with the portion, 2 of the steam-pipe A and between its ends is provided with a valve 6 It will thus be seen that the cylinder C communicates with the steam-pipe above and below the valve B. At a point near the top the cylinder is provided with an inlet f for filling the cylinder with lubricant, and said inlet is normally closed by means of a plug f. Pet-cocks g h communicate with the respective couplings a (l for a purpose hereinafter explained.

A plunger-rod D, preferably having a knob v at its upper end, passes into the cylinder 0 through the coupling a, pipe b, and a stufingboxj, located above said coupling. At the lower end of said rod D a plunger or piston E is secured. This piston comprises two flexible cups 1 m, the periphery of each being adapted to bear against the inner face of the cylinder 0 with a force commensurate with To operate the apparatus, close the valve c and open the petoock g, thus allowing pressure to escape from the cylinder above the cup-shaped piston E. The pressure under the piston will then cause it to be forced to the top of the cylinder. Then close the'valve e open petcock h, and allow pressure to escape from lower portion of the cylinder. The petcock h will then be closed, the plug f removed, and the cylinder filled with oil through the inlet f, and then the petcock Q will be closed. The valve c,which controls the admission of higlnpressure steam to the top of the eyl-inder,will then be opened, thereby applying full boiler-pressure of steam to the upders of theengineneeding lubrication.

per side of the piston E.

and be carried by this means into the cylin- It is evident that the cylinder 0 may be pro vided with any desired number ofoutletsfor lubricant. The lubricator will preferablybe provided with an indicator F and when the apparatus is provided with several outlets the indicators will be so arranged as to show the supply of oil being delivered to each ma chine. The indicator F comprises a glass tube 11, passing at its ends through stuffing boxes n, and plates n the latter being connected by a series of rods 02 which serve to protect the glass tube. The lower end of the tube a communicates with the pipe e by means of a short pipe 71 and the latter is provided with a valve or. The upper end of the tube or communicates, by means of a pipe niwith the portion 2 of the steam-pipe A and is provided with a valve 71 To operate the indicator, the valve Q will be closed and the valves 91 n opened. The glass tube 97, will fillwith water from condensed steam and the amount of oil delivered can be seen as it rises through the water.

It will be seen that byconstructing the piston E as above described it will always bear against the cylinder with a force or frictional contact commensurate with the pressure against it and forms, in effect, a double automatic packing for the piston against the interior of the cylinder and prevents the intercommingling'of high-pressure steam with the oil and renders the apparatus effectual, in every respect, in the performance of its functions.

It is evident that the device can be readily cleansed should occasion require it by opening the valves and permitting the steam to blow through it. Should some obstruction in the oil affect the proper feeding of the oil, the Valve e might be opened wider and the obstruction thus permitted to pass.

My improvements are very simple in construction, cheap to manufacture, and effectual, in all respects, in the performance of their functions. I
